v GEORGE FINNEY, DIE PLUIMMEB, IDAHO.

SAW-SET.

To allwhom it may concern: a

Be. it. known that I, GEORGE FINNEY, a citizen of the United States, residing at Plummer, in the county of Benewah and State of Idaho, have invented new and useful Improvements in Saw-Sets, of which the following is a specification.

The present invention relates to improvements in saw setting apparatus. p

The primary object of the invention is the provision of a saw setting apparatus which shall be of a simple, cheap and efiicientnature, and wherein the teeth of the saw may be easily and readily set at the desired angle.

I also propose to produce a saw set of this nature of a light but strong construction so "that the same may be conveniently carried in the tool boX of the operator and further shall. include an adjustable gage block mountedon the base for vertical adjustment and in opposition with the said head, thereby enabling the bending of the saw teeth at difierent angles.

A still further object of the invention is the provision of means supported upon the base which will permit of the operator observing the saw teeth when clamped in the setting apparatus, without the necessity of having to remove the saw therefrom.

A further object of theinvention resides in the provision of the setting head with a slot in which are mounted the teeth setting members, and means for holding the setting members in such slot, whereby movement of the same is prevented during the setting action of the saw teeth.

With the above and other objects inview, the invention consists in the novel features, details of construction. and combination of parts which will hereinafter be more fully set forth, illustrated in the accompanying drawing and pointed out'in the appended claims.

bearing plates, clearly illustrating the groove formed in the inner face thereof for receiving one edge of the glass.

Referring more particularly to the accompanying drawing, in which like characters of reference refer to corresponding parts in the several views, the saw setting apparatus is denoted generally by the character 5 and comprises a broadened bed plate 6 of substantially rectangular configuration having formed at one end thereof and contiguous therewith a vertical supporting arm 7 The opposite end of the bed plate 6 is formed with a vertically extending bearing lug 8 arranged in spaced parallelism with the supporting arm 7. Detachably connected to the vertical side edges of the bearing lug 8 through the medium of screws or other suitablefasteners 9 is a pair of bearing plates 10 having a Ushaped opening 11 opening out through the front edge 12 of .said plates and in which is mounted for longitudinal siding adjustment a setting head 13. Ihe said bearing lug S is formed with an axial internally threaded opening 14 in which is threadedly mounted the screw rod 15 having connection at its inner end with the setting head 13. The opposite or outer end of the operating screw is formed with a squared. portion on which the operating crank 16 is mounted, thus it will be seen upon operating the crank 16 it will impart movement to the screw 15, which in turn causes the adjustment of the setting head in a direction toward or from the supporting arm 7.

This setting head 13 embodies a broad rear cross plate 17 and a forward narrow cross strip 18, the cross strip 18 being disposed in spaced relation with the cross plate 17 defining between the confronting faces thereof a longitudinal slot 19 in which are plane below the plane of the top surface 01'. the bed plate 6, thus presenting or forming a transverse groove 23, thepurposeotwhich will be fully set forth as are 'des'trilatiion T the invention is proceeded With.

I employ in connection With a saw setting apparatu of the above stated character, a bloc: designated by the character 24 and of substantially U-form. Tl'iesa-id gage block When associated with the setting ap; parent's, .1'n"(')'u11ted on the siipportirrg arm 7 for 'vertieal adjustments. The gage block when in this position is bror-rght to bear against the inner faceof 'thesu ppo'rting arm with the legs 25 "thereof iztriaiiged against the opposite side faces of the supporting member and retained in adjusted position therewiththrough the n1edii1m of thumb screws -26. This gage block 24 is provided along its lower portion with a beveled con tact point 27 against Which the teeth are bent, for properly gaging the angle of bending the saw teeth. Of course, it will be understood that during the bending 'or "setting o l "the savv teeth, the saW is inserted between the confronting faces of the setting head and gage and the teeth are brought to bear against the beveled point 28 of'the setting members. I he bearing plates 8 'SHppO'ft the setting head 18 slightly above the top 'fae'e o'if tl1ebed plate for the purpose *ofaperinitting a transparent plate 29 being inserted on the bed plate 6 directly beneath the setting head and over the sight opening 30, formed transversely in the bed plate adja- 'eent one end tire-reef. This "construction 'Will permit of the operator observing at a glance 'the bending orlsetting operation of the saw teeth, Without the 'nece s's'ity I of removing the saw from the apparatus. The said transparent plate 29 is ofa length slightly greater th an"the transverse extent of the bed plate, defining the transverse ends of the trans p'a rent plate Within the grooves 31 of the bearing plate, While one longitudinal edge of the transparent plate is slidably mounted in the groove '32 formed in the inner face of the bearing lug. By this arrangement "the outermost lon i-tudinaledge ofth'ebea'rplate will contact with the facing of the 'gage block and thereby prevent any accidental movements of the transparent plat-e Wheninserted in the apparatus.
